Title: Television receiver power supply
IPC: H04N5/44
Filed: 1962-10-18
Abstract: 983,270. Automatic voltage regulators. MOTOROLA Inc. Oct. 18, 1962 [Nov. 8, 1961], No. 39495/62. Heading G3R. [Also in Division H2] . The operating potential, e.g. 16. 5 V, for the various stages 16, 12, 20, 24 of a transistorised television receiver is provided by the output, between ground and a terminal 48, of a power supply unit (see Division H2) and is derived either from the mains over a transformer 35 and rectifiers 40, 41 or from a battery 52, this potential being stabilized by a transistor 50 which carries the operating current and which is controlled by a further transistor 72 in dependence upon output potential variations. The base of transistor 72 is connected over a reference Zener diode 75 to a voltage divider 77, 78 shunting the output terminals of the power supply unit, and is also connected over a voltage divider 80, 82 to a source of relatively high negative potential, e.g.-84 V, derived from the stage 24 of the receiver. The arrangement is such that the diode 75, when conducting, stabilizes the base potential of transistor 72 with respect to terminal 48, so that variations in output voltage are reflected as changes in emittercollector current of transistor 72, which current changes will in turn cause changes in the base current of transistor 50 so that the conduction of transistor 50 varies inversely with output voltage variations, whereby the output voltage tends to be stabilized. When, however, the input voltage to the regulating system falls below the value associated with the conduction of the Zener diode 75, the transistors 72 and 50 are driven into saturation by the bias source available from the voltage divider 80, 82, so there is a minimum voltage loss across the emitter-collector path of the transistor 50.

Apparatus for discharging a vertical reaction shaft 16 comprises a shell 6 forming a downward extension of the chamber, rods or blades 1 movable transversely of the shaft by hydraulic motors 2, and a charge support 4 initially movable axially of shell 6 and forming part of a carriage having spindles 7 and 9 moving respectively in closed guide 10 and a guide 12 with a lower opening 13. The carriage is also formed with an arcuate groove 15 engaged by a spindle 8 displaceable in a guide 11 by hydraulic motor 14. Initial downward movement of motor 14 lowers support 4 until spindles 7 and 9 reach the bottom of their guides 10 and 11, whereupon motors 2 close the rods or blades 1. Further movement of motor 14 tilts the carriage, discharging material from support 4, whereupon motor 14 is reversed until said support 4 reaches its original position when motors 2 are also reversed to remove the rods or blades 1. The various movements may be controlled in sequence by a device incorporating electromagnetic valves. In a modification, Fig. 4 (not shown), the carrier is directly controlled by an hydraulic motor and another modification. Figs. 5a, 5c (not shown), has the shell movable with the carrier by an hydraulic motor on a carriage away from the chamber for discharge by tipping.

As shown a fuel supply line 96 fed by gravity from a sump (not shown) has a filter 97 interposed therein. The fuel pump 19 which is driven by an electric motor 110 delivers fuel to a control unit 15. The unit 15 includes a manually operated fuel control valve and a control switch 14 which not only controls the positioning of the valve but selectively energises the motor 110 of the fuel pump and a high tension ignition unit 112. Fuel under pressure is delivered from the outlet port 102 of the valve, when the latter is open, through the pipe 31 to the spray nozzle 26.
